How long after taking Flagyl for BV can I have ?

I completed my regimen of 500mg flagyl, 2 pills a day for 7 days to treat BV yesterday, and was wondering how long I have to wait before I have . The pamphlet I received did not specify. I know obviously I was not supposed to have while on the pills, which I didn't, but am wondering if everything seems to have cleared, when I am safe to have again? Thanks!
